INSOLE-TRIMMING MACHINE.

Specification of Letters Yatent.

Patented Feb. 8,1921.

Application led April 1, 1918. Serial No. 225,872.

To all whom it may concern.'

Be it known that I, FRANK C. FIX, a citizen of the United States,residing in Cincinnati, Hamilton county, Ohio, have invented a new anduseful Improvement in Insole-Trimming Machines, of which the followingis'a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in whichfFigure l is a side elevation partially in section of one form of myimproved machine. Fig. 2 is a diagrammatic sectional view on the lincII-II illustrating the gearing.

Fig. 3 isa front view of the machine.

Fig. 4 is a plan view of a reinforced insole, after it has passedthrough the machine, andV Fig. 5 is a detail sectional view on the lineV-V of Fig. 4.

This invention relates to an improvement in trimming machines forreinforced insoles, and is designed to provide an inexpensive andeflicient machine which will secure the reinforce to the insole, so thatafter the insole has been passed throughthe machine, the surplus stocktrimmed from the insole will adhere thereto. In machines of thischaracter the clippings or trimmed off portion would very frequentlyhang freely from the insole during its passage from the machine, andsometimes would be caught in the gearing and jam themachine. l

By theuse ofan improvement, such as shown and described, the trimmedportion will adhere to the insole, and is removed after the insole haspassed through the machine.

The precise nature of my invention will be best understood by referenceto the accompanying drawings, which will now be described, it beingpremised, however, that various changes may be made in the details ofconstruction and general arrangement of the parts, without departingfrom the spirit and scope of my invention, as defined in the appendedclaims. Y

In the drawings I have shown my improvement in connection with an insolereinforcing and trimming machine, such as.

shown and described in my co-pending application Serial No. 193,728, andin which the reference character 2 designates the framev of the machine.The frame of the machine is provided with standards 3 having bearingsfor the main shaft 4 and a countershaft 5. The main shaft is providedwith a fast and loose pulley, as well as a pinion 6, which meshes with aspur kgear 7 on the shaft 5.

The main shaft 4 is connected to a spindle 8, by means of bevel gears 9,which spindle co-acts with the feed wheel 10 and a; rotary table l1 forforming the lip on an insole. The feed wheel k10 is connected to ahorizontal spindle 12, which is positively driven through the medium ofthe gears 13 from the shaft 5, and connected tothe spindle 12 1s a bevelgear 14, which is arranged to rotate the table l1 through the medium ofthe gearing 15.

Adjustably connected to the frame of the machine is a knife bracket 16in which is adjustably mounted a trimming knife 17,

which is arranged to trim the reinforcing canvas, ror duck between thelip and the edge of the insole. Mounted for reciprocation in a-guide ina bracket 18 secured to themachine, is a stem 19 of a hammer 20. Thishammer 20 is reciprocated by means of a crank 21 on a shaft 22. Theshaft 22 is arranged to be driven by the-gears 23 from the main gearwheel 7.

The insole 24, such as shown in Fig. 4 ofthe drawing, is provided with areinforcing piece 25 of duck or canvas, the underside of which is coatedwith an adhesive, so that the duck is firmly secured around the lip andto the body of the insole by the adhesive. The insole, together with`the rel.

inforcing, is passed through the machine,

the feed wheel 10 and the spindle 8 forcing the reinforce into thecorners at the junctions of the lip and the insole, and while the insoleis being passed through ,the machine the surplus stock of the reinforceis trimmed between the lip and the edge of -with the insolebefore-passing tothe trimming knife to cause the clippings or trimmedmaterial to firmly adhere tothe insole. y
